TOOL.

Application med 'April 17, 1925. 7 Serial No. 23,861.

This invention relates to tools, and more particularly to a tool forhandling U-shaped elements and has for its primary object a simple andinexpensive tool for readily and efficiently attaching and detachingdifferent pending application of G, J. Houts,'Serial No. 745,093, filedOctober 22, 1924:,

As mentioned abovethe invention relates to tools for attaching ordetaching U-shaped clips for securing strands to a support and inaccordance with the general features thereof, there isprovided in oneembodiment thereof a lever, which is provided with a grooved surface forguiding the portion connecting the side portions of a U-shapedclip whileattaching it to or detaching it from a support, the opposite end of thelever being fulcrumed upon an adjustable member with a hook likeportion. for engaging thesupport. The member is normally maintained inan engaging position and a projecting member engaging the strands withinthe clip serves as a guide or stop in positioning the when fasteningtelephone switchboard cables to a supporting frame;

Fig. 2-isan enlarged plan view thereof,

and i l j l i v Fig; 3 is a vertical end view looking to,-

The invention herein illustrated and described is particularlyapplicable foruse in attaching to, or detaching from supporting frames,strand clamping members or clips, especially those embracing telephoneswitchboard cables, by the method disclosed in the copending applicationhereinbeforereferred to,.but it is to be understood that the novelfeatures of theinvention are capable of other applications.

Referring to the drawings wherein like reference numerals designate likeparts throughout the several views, 10 indicates a bar or lever providedat one end with an angularly' disposed portion 'll forminga handleforthe tool, The work engaging face of: the lever 10 is" provided withaplu' ra'lity of grooves 12 within one or the other of which a resilientportion. 13 of a clamping member or clipl iis entered when positioningthe tool preparatory to mounting the clipupon its "supporting member.The clip 14 illustrated in Fig. 1 is of a typesubstantially like thatdisclosed in several different forms in the hereinbefore mentionedapplicationto which reference may had for a more detailed descriptionthereof. The lever 10 at its right hand end is bifur cated in alongitudinal direction as'indicated at 17 and between'the arms 18 of thebifurcation and pivotally supportedupon a shoul dered screw 19 threadedinto one of the arms 18 is a member 20, the screw 19 forming the fulcrumfor the lever. The member 20 is provided with 'two separated openings 2]f as will be more fully set forthhereinafter.

The member 20'is provided witha hooklike portion 22 atone end forengaging the supporting framework to which the clip [leis to be attachedor detached I from, as clearly shown. inFig. '1. The hook likeportion 22comprises a right angle extension 23te'rminatingat its end in a portion24 extending parallel to the main portion ofth'e member The member 20 isnormally urged clockwise about the fulcrum of the lever for conveniencein mounting the tool, by the engagem'entbf the free end of a leaf spring26 secured to the underside of the*lever -10, as indicated at'27 (Fig.1'), with the free end of the spring 26 extendingupwardly through thebifurcation 17 p and engaging the left hand face of the member 20.Fo-r'the urpose of guiding the tool into positionwith respect to thestrandsbeing cla1nped,'in the present instance telephone switchboardcables, theupper face of the lever -10at one side has suitably securedthereto a projecting guide 28 comprising a lengthofwire formed intoaloop. g 1

The operation of thistoolis as follow 2 Referring toFig. 1 wherein atelepho'ne switchbo ard cable assembly is "shown, "30 indicatesaplurality of cables being clamped to a channel member 31extendingtransversely of the length of the cables by the clamping memberor clip 14' having bent or hooked portions 33 at opposite ends whichareadapted to be hooked over surface 34 of the channel 31. The cableassembly illustrated in Fig. 1 consists of two vertical rows, with fivecables in each row, but it will read ily be understood that whenclamping a row of three cables for instance, the working end of themember 20 should be shortened. This may be accomplished by fulcrumingthe lever 10 to the member at the free opening 21. In using the tool theoperator firstpositions a clip 14 around the cables 30 acent the closedface of the channel 31 and with one hooked portion engaging the topsurface of the channel, The hook portion 22 of the member 20 is thenalso engaged with the upper surface of the channel 31 andsubstantiallyat the same instant the guide28 engages the cables as shown in Fig. 1,in case the tool is properly positioned the portion 13 of the clip beingentered in one or the other of the grooves 12. In case the tool is notproperly positioned with respect .to the clip, it is moved along thechannel member until the guide 28 engages the cables, as

shown." In this position the clip l l will'be securely held between thelever 10 and the cables and thereafter by pulling upwardly upon thehandle 11, the, lever fulcruming upon the screw 19, the cables will belifted and compressed until thehook portion 33 of the clip rises abovethe channel member 31, whereupon the operator may move the hooked endover the upper surface l of the channel until itwill move downwardly andfirmly rest upon the channel in its engaging position as shown at the.left hand end of Fig. 1. -To disengage a clip 14 from the channel theoperator merely mounts thetool as described. hereinbefore and pullsupwardly upon the handle thereby raising the hook portion 33 to a pointwhere it may be disengaged from the surface 3a of the chan-' nelbymoving it transversely thereacross.

In Fig. 1 the cables 30 are shown as suspended from the channel 31 butit is sometimes convenient and frequently necessary to support andsecure the cables upon the upper face of the channel member or toarrange the cables in vertical assemblies fastened to suitable supportsand. it will be readily apparent that the tool hereinbefore describedmay be used equallywell for such purposes;

; From the foregoing, description it will be seen that the tooldescribed is of coinclearly understood. that the tool can beused fordifferent types of clamping meinbers'for engage a support therefor, amember providing a fulcrum point for the lever and having a portion foroperatively engaging the said support, and means for normally holdingsaid. member in a v predetermined position relative to the lever-.1 f
